Read it through once

I must keep to my post, however. I must watch this ghastly countenance—these blue, still lips forbidden to unclose—these eyes now shut, now opening, now wandering through the room, now fixing on me, and ever glazed with the dulness of horror. I must dip my hand again and again in the basin of blood and water, and wipe away the trickling gore. I must see the light of the unsnuffed candle wane on my employment; the shadows darken on the wrought, antique tapestry round me, and grow black under the hangings of the vast old bed, and quiver strangely over the doors of a great cabinet opposite—whose front, divided into twelve panels, bore, in grim design, the heads of the twelve apostles, each enclosed in its separate panel as in a frame; while above them at the top rose an ebon crucifix and a dying Christ.
